Communicating with a PLC-5 Processor on a DeviceNet Network using Explicit Messaging
Publication 2755-6.8
Use the Explicit Message Program Control feature to configure
device parameters on your DeviceNet network via the ladder logic
program in the PLC-5 processor that is controlling these devices.
You can use Explicit Message Program Control only with devices
that are slaves of your 1771-SDN Scanner Module. These slave
devices must be mapped in the scanner module’s scan list.
Use the Explicit Message Program Control feature to:
•
transmit configuration data from your scanner module to its slave
devices on your DeviceNet network
•
receive status and diagnostics from these devices on your
DeviceNet network
•
make runtime adjustments to device parameters according to
changing conditions detected by your processor
